Quick comprehension check

In the diagram, line a and line b are parallel and are intersected by a transversal. If angle 1 is 110° and is located on the exterior of the parallel lines, find the measure of its alternate exterior angle, angle x, which is also located on the exterior of the parallel lines but on the opposite side of the transversal.
